Until version 2, Expression Web was the only application in the Expression Studio suite based on Microsoft Office code and dependencies.

Microsoft Expression Web 3 was released in 2009. No service packs were released for version 2, but in December 2008 it received an update that fixed a problem that prevented macros from running on Windows Vista-based client computers. Expression Web 2 offers native support for PHP and Silverlight. Microsoft Expression Web 2 was released in 2008.

Expression Web does not have the form validation controls for HTML fields like FrontPage, but supports validator controls for ASP.NET. The first and only service pack was published in December 2007. The Release To Manufacturing version was made available on December 4, 2006. Beta 1 removed most of the FrontPage-proprietary (non-standard) features such as bots (use of FPSE features for server-side scripting), parts, functions, themes, automatic generation of navigation buttons, FrontPage forms, navigation pane to build a web site's hierarchy, and other non-standard features available in CTP 1. On September 5, 2006, Microsoft released Beta 1. On May 14, 2006, Microsoft released the first Community Technology Preview (CTP) version of Expression Web, code-named Quartz.
